HOG-DEH AIBING STRUCTURE.

Specification of Letters Patent.

Patented June .18, 1918.

Application filed July 13, 1917. Serial No. 180,465.

To all whom it may concern:

Be it known that I, Rosniz'r E. JORDAN a reference to ho dehairing structures.

The object o the invention is to provide a structure in which the beater-elementsare guished from a rigid secureinent of the beater-elements to the. mounting, whereby any tendency to develop abreakinf strain on the structure prolonged.

A- further object of the invention is to present an assembled structure, comprising a mounting and a series of beater-elements hingedly connected thereto whereby such elements may have a swingin movement on axes which are parallel to t c axis of the rotatable mounting to which they are atmovement bein in relation to the mounting in order to 0 viate any tendency of the element to breakat a particular omt intermediate of its ends.

Still anot er and more specific object within the contemplation of the invention is to' provide a metallic mounting having radiating portions, to one of which is attached a reinforcing element of flexible material, preferably, and juxtaposed to which is a beater-element hmged y connected to the mountin and normally maintained in an outstandin position by one of the radiating portions, t e beater-element also being of flexible material, preferably.

Other objects and advantages of the invention will be seen to be inherent in the proposed structure, and still other objects and advantages will appear from the following description.

' This invention seeks, in general, to provide an animal-dehairing structure which is peculiarly adapted for use in dehairing and polishing hogs effectively and without inury to the carcass; this structure, from an operative standpoint, possessing a high degree of durability and efliciency, while yet of great simplicity.

disposed on a rotatable mountingso as to be hingedly connected thereto as distin-Q parts is minimized and the li e of the Drawings are hereto appended to illustrate some of the possible embodiments and utllizations of the invention; and it is to be understood that these embodiments and utilizations may be considerably varied, and that other possible embodiments and utiliza-' trons may be employed, all utilizing the underlying principles of the invention and falling within the spirit thereof and within the objects contemplated thereby.

In these drawings:

Figure 1 is a view in elevation, partly 1n section, of the beater-structure, one set of the beaterelements and reinforcing elements, carried thereby, appearing in dotted lines in the position they may assume as the beater-instrumentality is rotated 2 is a view in top plan of the same; Fig. 3 1s a fragmentary view, in section, on an enlarged scale, of a part of the mountmg and the beater and reinforcing elements attached thereto;

Fig. 4; is a similar view, showing the beater-element in its swung or operative position;

Fig. 5 is a fragmentary view of the bin e connection between the mounting and t e beater-element end e fied form of hinge connection between the beater-elements and the mounting; and

Figs. 8 and 9 are fragmentary views in end elevation showing other modifications.

In hog-dehairing and polishing machines, of present-day construction, the beater-elements are usually clamped rigidly in a mounting and, by reason of the fact that they rotate at the rate, say, of 165 revolu tions per minute, these beater-elements upon coming into contact with the-carcass tend to develop a hinge reaction at a point adjacent to that at which the elements are clamped, and the conse uence is that these elements will naturally reak at that point and become useless in a comparativel short time; the manner of connecting the eaterelements, in my improved construction, efficiently obviates this danger.

In Figs. 1 to 5, I have illustrated a preferred embodiment of the invention as comprising a novelform of mounting and a novel means of securing the beater elements therein, as will now be described.

The mounting, designated generally by the reference-character 1, includes a set of aggrouped castings, each comprising a body-- 6. and 7 I have shown a modified.

portion 2, a straight radiating portion. 3,

anda curved radiating portion 4. As. seen in Fig. 1, these portions '3 and 4 are aggrouped as companion ortions, and are held in such relation by a olt 5. By reason of the fact that these two portions are angu-' Swinging onthe bolt 7 and having its form of hin j connection between'the beater element an. the axis 7 this modification f. involving a wire 15 or other appropriate instrumentality extended through the inner end of the beater-element 10.

.- In Fig, 8 I' have disclosed a modification of .an entirely different character,' this in- '-'volving the hinging to amounting 16 ofa prising a radiating straight portion 18 and:

ends thereon, is a beater-clamping member; 8, which is provided with prongs 9 which penetrate the lower portion of a beater-element 10.

J uxtaposed to the beater-element, and se.-

cured to the curved radiating portion 4, as. by a bolt 11, is areinforcmg element 12.

The beater and reinforcing elements are preferably formed of flexiblev material, such as rubber belting. The beater-elements, at

their outer ends, carry .hairremoving scrapers 13. i As well seen in Fig. 3, the beater-element .Thehead is adaptedto be embraced by suit-- holder designated, generally, 17, and coma radiating curved portion .19- between which is disposed a beater-element 20- and a-reinforcing element 21' similar to the beater andv reinforcing elements 10' and 12 In this instance, the holding structure 17 is-) not integral with the mounting 16, as in the embodiment of'Figs. 1' to 7; but it contem lates connecting the holding structure to't e mounting in such manner that the formermay have a slight swinging movement on the latter: To this end, the casting rovided with. extensions 22 and 23,

16 is suitab y secured together. and formed at their. outer ends so as to present ahead 24.

ably-formed portions 25' and 26, such that is so mounted on its axis 7 and in relation to the adjacent surface of the radiatingpon tion 3 and of the reinforcing element 12 that there is a slight clearance or space between these surfaces to permit the beater-element to move on its axis. 7 with res set to the .radiatingportio'ns and the rein orcing el'ement. By this construction, when the structure is rotatingas in aclookwise direction element; wherefore the likelihood of break-.-

the resulting centrifugal action tends to swing each of the beater-elements on ts respective axis; but this swinging movement is in part resisted by the reinforcing ele-'.

By reason of the swinging movement of "the beater-element 10 on its axis,-

and the fact that it is not rigidly clamped in the mounting, this-beater-element does not bend into an angular condition at any point, because this is precluded by the fact that it, in its entirety, swingson its axis; and there is in consequence no bending or straining point developed in the beatering or weakening of the beater-element intermediate of its ends is efficiently minimized, and there is, therefore, no hinge reaction produced on the element itself.

permit a swinging movement 0 they may have a hinging movement on the head 24, such' movement being limited by engagement of the lower ends 27 and 28,

respectively, of. the portions 25 and 26 with the sides of the extensions 22 and 23,. respectively. This arrangement provides for a slight swinging of the heater and reinforcing elements, and their holder, on the loo mounting, it being. understood that the f beater-element 20, in this instance,'may be of the construction illustrated in Fig. 3,

for instance, or the manner of mounting the similar to that disclosed in my. co-pending application, Serial No. 152,423. This construction, of Fig. 8, is adapted to relieve any undue strains that may at anytime be imposed upon the holding structure and mounting when the beater element impinges against the carcass in performing its function'of dehairing and polishing the same.

In Fig. 9, this feature of providing for movement between the holding structure and the mounting is also embodied; but, in this instance, the mounting 29 carries em-' bracing portions 30 adapted to hold the rounded ends 31 and 32 of radiating. por- From the foregoing, it will be perceived that I have devlsed an eificient'structure in which the tendency of impingement of the beater-elennent against a carcass to develop a bending and breaking point intermediate of the ends of the beater-element is prevented; the bin ing action between the beater-element an the mounting tending to the beaterelement on a efined axis and, thus, permitting the beater-element to remaI'm in a normally outstanding position without angular bending that would otherwise produce a breaking point.

What I claim is:

1. A beater structure including a mounting, a reinforcing element secured thereto and extending radially therefrom and having a swinging movement in respect to the mounting, and a flexible beater-element hingedly connected to the mounting and having a swinging movement in respect thereto and in relation to the reinforcing element and bendable beyond the limits of the mounting and against the reinforcing element.

3. As an article of manufacture, a mounting including radiating portions, a reinforcingelement mounted on one of the portions and radiating from the mountin and a flexible beater-element also radiatlng from the mounting, hin edly connected thereto, and having a hen ing action in respect to and against the reinforcing element.
